All Links Are Sublinks of Arithmetic Links
While it is known that every closed orientable 3-manifold M contains an arithmetic link L (since the figure-eight knot complement is both arithmetic and universal), Theorem 2 asserts that L can be chosen so that M \ L is homeomorphic to the complement of a link in S3. Recall that a link L in S3 (resp. in M) is hyperbolic if S3 \L (resp. M \L) is homeomorphic to H3/Γ, where H3 is hyperbolic 3-sp...
متن کاملIf P != NP Then Some Strongly Noninvertible Functions Are Invertible
Rabi, Rivest, and Sherman alter the standard notion of noninvertibility to a new notion they call strong noninvertibility, and show—via explicit cryptographic protocols for secret-key agreement ([RS93,RS97] attribute this to Rivest and Sherman) and digital signatures [RS93,RS97]—that strongly noninvertible functions would be very useful components in protocol design. Their definition of strong ...
متن کاملOn language equations with invertible operations.dvi
The paper studies language equations of the type X ⋄ L = R and L ⋄ Y = R, where L and R are given languages and ⋄ is an invertible binary word(language) operation. For most of the considered insertion and deletion operations, the existence of both a solution and a singleton solution to these equations proves to be decidable for given regular L and R. In case L is a context-free language and R i...
متن کاملComputational results on invertible matrices with the maximum number of invertible 2×2 submatrices
A linear 2-All-or-Nothing Transform can be considered as an invertible matrix with all 2 × 2 submatrices invertible. It is known [P. D’Arco, N. Nasr Esfahani and D.R. Stinson, Electron. J. Combin. 23(4) (2016), #P4.10] that there is no binary s×s matrix that satisfies these conditions, for s > 2. In this paper, different computational methods for generating invertible binary matrices with close...
متن کاملOn noninvertible mappings of the plane: Eruptions.
In this paper we are concerned with the dynamics of noninvertible transformations of the plane. Three examples are explored and possibly a new bifurcation, or "eruption," is described. A fundamental role is played by the interactions of fixed points and singular curves. Other critical elements in the phase space include periodic points and an invariant line. The dynamics along the invariant lin...
